Kell,
I go through this so much too. And sometimes I start to feel like she is a mother... I conjure up emotions towards her and just get smacked around psychologically yet again...
I also feel completeley unlikeable, in spite of being generally well-liked. When I am with her, I get nothing but discussions of my body (what is good or bad about it... and how it compares to hers at my age - most of which is something she has created in her mind). I get the constant mantra that "I don't need to work," - she refuses to believe that I enjoy working (she thinks it is undignified I guess... except if you are a dr like my sis).
Kelly, I know she doesn't see me as a real person. Whenever we see each other again, she stares at me like I am a new species. She has created a person in her miond and I don't match her creation. I think it is harder because you are so near your mom, Kell.
Take care and remember not to use your mom as a measuring stick. That's like measuring light years with a tablespoon.
Love, Beth
